Specific details on test material used for the study:
- Storage condition of test material: approximately 4°C in the dark under nitrogen
Auto-ignition temperature:
ca. 256 °C
Atm. press.:
>= 98.8 - <= 102.31 kPa
Conclusions:
This parameter/method is not relevant for classification, however the information is useful regarding process safety and potential additional fire hazard.
No particular hazard is anticipated in normal conditions of storage.
Executive summary:

The auto-ignition temperature of the test substance was measured under GLP according to IEC 79-4 method (listed in EU A15 guideline).

The auto-ignition temperature was determined by heating aliquots of the test material in a flask and observing for any ignition.

The test material has been determined to have an auto-ignition temperature of 256 ± 5°C at atmospheric pressure.

Description of key information

No particular hazard is anticipated in normal conditions of storage.

Key value for chemical safety assessment

Autoflammability / Self-ignition temperature at 101 325 Pa:
256 °C

Additional information

A fully reliable experimental study, conducted according to a recognized IEC/EU method and under GLP, is available. It is considered as a key study. The result is retained as key data.

This parameter is not relevant for classification, however the information is useful regarding process safety and potential additional fire hazard.
